1e59e18d73 test: Composite with solid images instead of using pixman_image_fill_* 
There is a couple of places where the test suite uses the
pixman_image_fill_* functions to initialize images. These functions
can fail, and will do so if the "fast" implementation is disabled.

So to make sure the test suite passes even using
PIXMAN_DISABLE="fast", use pixman_image_composite32() with a solid
image instead of pixman_image_fill_*.

aea0522f6f MIPS: DSPr2: Fix bug in over_n_8888_8888_ca/over_n_8888_0565_ca routines 
In main loop (unrolled by factor 2), instead of negating multiplied
mask values by srca, values of srca was negated, and passed as alpha
argument for

    UN8x4_MUL_UN8x4_ADD_UN8x4 macro.

Instead of:

    ma = ~ma;
    UN8x4_MUL_UN8x4_ADD_UN8x4 (d, ma, s);

Code was doing this:

    ma = ~srca;
    UN8x4_MUL_UN8x4_ADD_UN8x4 (d, ma, s);

Key is in substituting registers s0/s1 (containing srca value), with
t0/t1 containing mask values multiplied by srca.  Register usage is
also improved (less registers are saved on stack, for
over_n_8888_8888_ca routine).

The bug was introduced in commit d2ee5631 and revealed by composite test.

55698584be configure.ac: Fail the ARM/iwMMXt test if not compiling with -march=iwmmxt 
If not compiling with -march=iwmmxt, the configure test will still pass,
thinking that the __builtin_arm_* intrinsic is a function instead of
generating a single instruction. Since no linking is done, the configure
test doesn't catch this, and we get linking errors in the build.

7d4beedc61 mmx: add and use pack_4x565 function 
The pack_4x565 makes use of the pack_4xpacked565 function which uses pmadd.

Some of the speed up is probably attributable to removing the artificial
serialization imposed by the
	vdest = pack_565 (..., vdest, 0);
	vdest = pack_565 (..., vdest, 1);
	...
pattern.

2ddd1c498b mmx: add src_8888_0565 
Uses the pmadd technique described in
http://software.intel.com/sites/landingpage/legacy/mmx/MMX_App_24-16_Bit_Conversion.pdf

The technique uses the packssdw instruction which uses signed
saturatation. This works in their example because they pack 888 to 555
leaving the high bit as zero. For packing to 565, it is unsuitable, so
we replace it with an or+shuffle.

facceb4a1f mmx: Use Loongson pinsrh instruction in pack_565 
The pinsrh instruction is analogous to MMX EXT's pinsrw, except like
other Loongson vector instructions it cannot access the general purpose
registers. In the cases of other Loongson vector instructions, this is a
headache, but it is actually a good thing here. Since the instruction is
different from MMX, I've named the intrinsic loongson_insert_pi16.

6d29b7d755 mmx: don't pack and unpack src unnecessarily 
The combine function was store8888'ing the result, and all consumers
were immediately load8888'ing it, causing lots of unnecessary pack and
unpack instructions.

It's a very straight forward conversion, except for mmx_combine_over_u
and mmx_combine_saturate_u. mmx_combine_over_u was testing the integer
result to skip pixels, so we use the is_* functions to test the __m64
data directly without loading it into an integer register.

For mmx_combine_saturate_u there's not a lot we can do, since it uses
DIV_UN8.

4e0c7902b2 mmx: make ldq_u take __m64* directly 
Before, if __m64 is allocated in vector or floating-point registers,

	__m64 vs = ldq_u((uint64_t *)src);

would cause src to be loaded into an integer register and then
transferred to an __m64 register. By switching ldq_u's argument type to
__m64 we give the compile enough information to recognize that it can
load to the vector register directly.

This patch is necessary for the Loongson optimizations when __m64 is
typedef'd as double.

e24c1c849d bits_image_fetch_pixel_convolution(): Make sure channels are signed 
In the computation:

    srtot += RED_8 (pixel) * f

RED_8 (pixel) is an unsigned quantity, which means the signed filter
coefficient f gets converted to an unsigned integer before the
multiplication. We get away with this because when the 32 bit unsigned
result is converted to int32_t, the correct sign is produced. But if
srtot had been an int64_t, the result would have been a very large
positive number.

Fix this by explicitly casting the channels to int.

We're using a patched gcc-4.5, and having to modify configure.ac and

iwMMXt intrinsic support is equally broken, and we test a known broken
intrinsic in the configure test program, so the version check is rather
meaningless.
